Filed: 1945-06-17
Abstract: 598,977. Wave-guides ; directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 11, 1945, No. 14802. Convention date, June 9, 1944. [Class 40 (v)] A device for propagating a beam of radio waves and for oscillating said beam through a pre-determined angle, comprises a rectangular wave-guide 1 fed from a high - frequency source, not shown, and connected to a wave guide section 3 which is terminated in a wave guide section 5 having inserted in it a wedge 7 of suitable material to minimise reflection. The section 3 has in one side wall a number of apertures 9 leading to smaller apertures 13, the sizes of the apertures being chosen in accordance with the desired characteristics of the beam. The effective size of apertures 9 is increased by the insertion of dielectric members 15. The upper side of guide section 3 is closed by a rotatable cylinder 17 formed with grooves 19 the width and distance .apart of which are less than a quarter wavelength, while the depth of each groove varies from zero to one quarter wavelength. The effectiveness of the closure of guide 3 by cylinder 17 is increased by quarter wave slots 23. In operation, cylinder 17 is rotated by motor 25, so that as the depth of the grooves 19 closing the top of guide 3 varies, the effective wavelength is varied, thus to vary the phase of the energy radiated through apertures 9. This results in the beam being swung back and forth through a predetermined angle. The form of the grooves 19 may be varied to make the angular movement follow a desired law, which may include stepwise as well as continuous deflection.

IPC: B43L13/20
Filed: 1947-06-06
Abstract: 627,140. Calculating-apparatus. MURRAY, F. T. June 6, 1947, No. 14986. [Class 106 (i)] [Also in Group XX] A device for plotting transition-curves and computing associated data therefrom, which curves may be of the kind described in Specification 585,204, comprises a celluloid sheet 11 preferably triangular in shape, having a straight base line 17, a curved edge 14 shaped to conform to the transition curve from the origin 16 on the base line and a straight scale 21 of radii having graduations, the distances of which along the scale correspond to the radii of the curve at selected successive points, the graduations being marked to correspond with graduations along the curved edge showing the corresponding points thereon, and a straight scale 24, which may be an extension of the scale 21, the graduations of which correspond with the amount of " shift," that is, the differences between the perpendicular heights from the base line of the centres of curvature and their radii. As shown, these graduations are marked in terms of the angle the tangent to the curve at the selected point makes with the base line. The figures may be alternatively marked so as to facilitate reading from either side of the sheet 11. Additional scales may also be provided, namely, a scale of length 23 adjacent to the radii scale 21, a scale 25 showing the distances (Ms) along the base line from the origin of the curve to the perpendiculars on the base line from the centres of curvature, a scale 26 showing the distances (X) from the point of origin of the curve along the base line to the perpendiculars on the base line from correspondingly marked points on the curve, a scale 27 showing the heights (Y) of the various points on the curve from the base line, a scale 28 showing the distances (M) along the base line to the perpendiculars on the base line from the centres of circles (a) which are tangential to the curve and to the base line and a scale 29 showing the lengths (Z) of the chords between the point of origin and the various points along the curve. Scales 24, 25, 26, 27, 28 and 29 are all graduated in terms of the angle made by the tangent at the corresponding point with the base line and a figure may be inscribed on the sheet 11 to illustrate the relationship of the various dimensions measured by the scales.
Patent GB-150735-A (GB)
Abstract: 150,735. National Cash Register Co., (Assignees of Pein, E. J. von). April 28, 1919, [Convention date]. Cash registers; differentially-moved indicators; flashes; printing iotals and sub-totals. - In machines wherein entries are accumulated upon a totalizer, the total may be indicated to the operator and the public at any time by the operation of a crank-handle. The invention is described as applied to the machine described in Specification 142,436, wherein are two totalizers, one for aggregating the purchase items of an individual customer and the other for registering grand totals. In accordance with the setting of a special key 307 and by the operation of the total-printing handle, either of these totals may be printed and simultaneously indicated. The total indicators are of the drum type and are duplicated to show in opposite directions. The drum elements are connected by gearing 259, 260 with pivoted toothed sectors 186 differentially moved, when the totalprinting crank is operated, according to the positions of the corresponding totalizer wheels, bv means of stepped plates 54 and yokes 55. The drums are retained in set position by pawls 278 and are released at the next operation of the machine by a pivoted frame 282 connected with the rocking-frame 66, which is oscillated by depression of the item keys or through the medium of the frame 155 and rod 193 bv rotation of the total-printing crank. The total-indicator drums are normally in gear with, so as to be set by, the customer's totalizer, but when a grand total is to be printed the plunger key 307 is pushed in so as to move the yokes 55 from engagement with one into engagement with the other totalizer, as described in the Specification referred to. At the same time through an arm 335 and a lever 337 an indicating-drum 255 is rotated to bring a distinguishing letter into the reading line. This is effected through a spring-controlled connecting-rod 343 which is held and released by the frame 66 in a manner similar to that employed for the usual item-indicating tablets 64. A flash 287 is rocked to reveal the indications (Fig. 4) by connexion through a rod 299 with the rocking-frame 194 operated from the total printing crank-shaft. The flash is held in this position by a spring-mounted pawl 290 which is shifted to release the flash again by means of a link 289 pivoted to the rocking-frame 282.

Title: Optically inspecting a band of material

IPC: G01N21/89
Filed: 1965-04-09
Abstract: 1,103,491. Photo-electric flow detection. EASTMAN KODAK CO. April 9, 1965, No. 15129/65. Heading G1A. To detect streaks running in a photographic film substantially along its length a single row of infrared sensitive resistors arranged across the width of the moving film is oscillated in the line of the row by not more than two detector widths so that infrared light specularly reflected from an area of the film containing the streak is received first by one detector then its adjacent one to produce a signal at the frequency of the oscillation and therefore indicative of a streak and not a speck which would produce a signal of a much higher frequency governed by the speed of travel of the film. In other arrangements the row of detectors is stationary and the parallel rays of lightilluminating the surface of the film oscillate angularly so that light from one area of the film  is directed first to one detector then to its adjacent one, or alternatively both illumination means and the detectors may be stationary and the film caused to oscillate transversely in addition to moving. In all arrangements the detectors are divided up into groups along the row and one detector from each group, not necessarily the corresponding one of each group, is connected to an amplifying channel so that two adjacent detectors are not in the same channel to otherwise cancel each other out if detecting the edge of the streak. The amplifying channels are frequency selective to give particular prominence to either streaks or specks and the final positive or negative signals are fed via biased rectifiers to positive and negative bus-bars, the degree of bias determining the sensitivity of the system. All signals from the bars are fed to a memory store controlling the destiny of the film thereafter. One half of the detectors are connected to positive potential and the other half to negative potential to compensate for any fluctuations in the potential supply or lamp intensity.

Abstract: 612,737. Washing-machines. HOOVER, Ltd. May 20, 1946, No. 15189. Convention date, June 8, 1945. [Class 138(ii)] The rotary agitator of a washing- machine comprises a disc 12 which is mounted for continuous rotation in a side wall of a liquid container 10, the disc being disposed so that it will normally be submerged in the washing liquid and with the whole of its circumferential edge lying close to the side wall of the container or a part thereon so as to prevent articles being washed from entering the space behind the disc. As shown in Figs. 1 and 2, the container 10 has a semi-cylindrical base 10a with vertical walls 10b, 10c, and the disc 12 is mounted on a shaft 13 with its circumferential edge disposed close to the wall 10c and in a shallow recess 15 in the wall. The exposed surface of the disc is substantially flat, apart from two radial depressions 12a therein adapted to provide an intervening rib 12b. In the arrangement shown in Fig. 4, the disc is not disposed centrally of the wall 10c and the base of the container is shaped to accommodate the modified position of the disc. The container may be provided with a flat, instead of a rounded base, in which case the disc is mounted in a vertical wall when the container is of square, rectangular or circular shape in plan, or it may be mounted on a slightly-inclined axis adjacent to a bottom corner of the container as shown in Fig. 8; both when the disc is arranged as shown in Fig. 8 and when it is arranged in a cylindrical container, a plate or shroud may be provided in the wall of the container close to the circumferential edge of the disc. In another construction, the upper part of the container may be of reduced cross-section so as to provide an overhanging ledge above the disc, which is then mounted in a recessed portion formed by an annular rib on the wall of the container. Alternatively, the edge of the disc may be lipped as shown at 36, Fig. 12, for cooperating with a boss 35 on the wall of the container. If desired, a rotary agitator may be arranged on each of the two opposite vertical walls of the container, or, as shown in Fig. 15, two agitators may be mounted in inclined portions 25b of the side walls 25a of the container; in these constructions, the agitators may be provided with three ribs.
